Adds the <new-file> operation to the fs_tool. When configured, the
<new-file path="...">...</new-file> tag will cause creation or overwriting of
the file given through the 'path' attribute. The file will contain the text
content of the tag.
Ref #4032
This patch moves the utility from the app/text_area to os/vfs.h to make
it easier to use by other components. By hosting the 'New_file' as a
friend alongside the 'Directory', we can now pass a 'Directory' as
constructor argument, which is consistent with other utilities such as
'File_content'.
As a further improvement, the new version supports the implicit creation
of the directory hierarchy leading to the new file.
Issue #4032
By adding an attribute 'size="yes"' to a query, one instructs fs_query to
report also the size of each queried file as attribute 'size' of the
corresponding 'file' node.
Ref #4032
The fs_query component used to try watching all files it found resulting in
errors on files that are not watchable. For some files, however, the watch-
feature doesn't make sense as they are not readable (no content, no size).
Now, fs_query will check first whether a file is readable and skip watching
if it isn't.
Ref #4032
When configuring fs_query to print the content of files it used to try so for
all files it found resulting in errors on files that are not readable. Now,
fs_query will check first whether a file is readable and skip printing the
content of those that are not.

Managing ssh event file descriptors was performed from two different
threads which could cause reallocation of structure used in other thread
in a call to 'poll' function.
Splitted initialization to parts and moved ssh event part into ssh loop.
Issue #4095
Moved creating ssh loop thread after initialization of wake up server
file descriptors to make sure that they will be properly handled even in
first loop run.
Issue #4095
The default size is on most kernels 512M. On OKL4 we have to use 800M,
because of the statically configured memory ranges in the OKL4 kernel.
By avoiding a specific amount of memory, the default Qemu memory sizes are
used.
Issue #4095
This patch fixes a GCC-10 compile error. Even though the optimization
was quite effective - I measured a speedup of factor 2 - it is not all
that important for the overall application performance. In the nano3d
case, we are talking about 1 vs. 2 percent of CPU time.
Fixes#4140
pthread.0 acquires a write buffer mutex and calls potentially
blocking fs operations. The EP thread handles session requests and tries to
acquire the same write buffer lock. IO progress events for pthread.0 are
handled by the EP thread, which however is blocking on the write buffer mutex.
The commit uses two write buffers, one which is filled by the EP and a second
which is used by pthread.0. The two buffers are swapped protected by a mutex
without invoking blocking fs operations.
Issue #4095
The exec_terminal generates a config report which is used as input ROM for
sandbox/init, which does not support an "<empty>" node.
An empty config node is empty, without an node.
Issue #4095
Was still using the event_filter.config from drivers_interactive-pc
although a dedicated file is present in the raw archive.
The fix is just for consistency reasons, as sculpt manager is generating the
event_filter.config anyway.
This patch increases the RAM quota of the top-level nitpicker instance
to 12 MiB so that resize operations can be buffered for resolutions up
to 2560x1080. It mutes diagnostic messages of the form "Warning: Gui
(...) not enough RAM to preserve buffer content during resize" and
improves the window-resize experience.
With this patch, the user is able to re-gain access to the inspect view
by toggling the inspect button of a file system unrelated to the failed
USB storage device.
Fixes#4090
The direct execution of application-level code by a watch handler is
troublesome because those handlers are executed at the I/O signal level.
In the concrete case, the watch handler got recursively called because
the handler called _handle_config (application-code), which called the
VFS, which in turn performed a wait_and_dispatch_one_io_signal, which
again invoked the watch handler.
The patch works around the problem by letting the watch notification
trigger the application-level signal for the _config_handler.
Fixes#4091
* The device XML information dataspace is only provided,
when the client's policy states `info="yes"`
* The device XM information gets changed to include the
physical resource names (I/O memory and IRQ addresses)
instead of virtual ids and page offset
Fix#4077
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of
- Platform::Device - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq - interface for receiving device interrupts
The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.
Fixes#4075
This patch adjusts the matching of the IP address such that the external
IP address is used as opposed the the NAT-local address. It is follow-up
fix of the conversion to the uplink session interface.
Issue #3961
Apparently the skewed motion timings came from the issue fixed by
"timer: restore semantics of periodic timeout 0". With the current
version of the timer, the original motion parameters work just fine.
This patch restores the ability to launch nitpicker within a gui_fb
window. It is a follow-up fix for "nitpicker: make framebuffer and input
optional".
Issue #3812
This patch enables sculpt to utilize the CPU reset mechanism via the
PS/2 controller as well as the information provided via the ACPI FADT
information. Whenever the /config/system file is changed to <system
state="reset"/>, both mechanisms are triggered.
Supporting both mechanisms is useful because the PS/2-based reset does
not work reliably on modern machines. The PS/2-based reset is useful in
the case when the FADT reset information refers to the PS/2 command
port. In this case, the platform driver is unable to access this port
because it is already handed out to the PS/2 driver. In this case, the
PS/2 driver kicks in.
Issue #2726
This patch adds the handling neccessary for clients to upgrade the cap
quota of their GUI session. Until now, the upgrade mechanism supported
only RAM quota.
The limitation became visible once a client - in the particular case the
motif_decorator - attempted the cap upgrade of its GUI session. The cap
quota would arrive at the wm, but the wm would keep it instead of
forwarding the quota to nitpicker. This resulted in an infinite retry
loop at the motif_decorator, ultimatedly depleting all its cap quota.
The window manager infers the overall state from the intercepted input
events for the decorator and all GUI clients. However, each of those
parties have an independent input-event stream. Whereas the order of
events within one GUI session is strict, the order of events between GUI
sessions is arbitrary. The window manager wrongly relied on a global
event ordering to track the pointed-at GUI session.
The patch removes the assumption of a global event order by tracking the
relevant pointer state for each GUI session independently and evaluating
these states when propagating the pointer position to the decorator.
Fixes#4059
